Some discussion on it's origin, but most attribute this neat matuka to David Collyer. Getting some more mileage out of the craft store bronze mallard sub. Can't do better than Mr. McPhail for instruction

A vintage pattern attributed to the Rev. Edward Powell. Instructions also call for it be tied with opposing partridge hackles; I prefer this Jingler variation. With a few mods, this would make a decent Spruce Moth.
